Paper Abstract

We designed a new optical fiber current sensor based on the Faraday Effect. The electronic detection scheme uses two polarizers in order to avoid ambiguities due to polarimetric detection. In this way we may detect current beyond the folding point of the square cosine law inherent to that sensing technique. The sensor presents excellent linear response in the measured range, front 0 to 7.5 kA (peak to peak) , 60 Hz AC current.
